NCP3012 Synchronous PWM Controller

Pin Pin Name Description 1 VREF The VREF pin is the output for a 1.25 V reference (1 mA max). A 100 kW resistor in parallel with a 1 mF ceramic capacitor must be connected from this pin to GND to ensure external reference stability. 2 EN The EN pin is the enable/disable input. A logic high on.

NCP3012 Synchronous PWM Controller The NCP3012 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.8 V. The NCP3012 provides integrated gate drivers and an internally set 75 kHz oscillator. The NCP3012 has an externally compensated transconductance error amplifier with an internally fixed soft start. The NCP3012 incorporates output voltage monitoring with a Power Good pin to indicate that the system is in regulation. The .
